2012 National Public Water Systems 

Compliance Report

Executive Summary

The United States (U.S.) Environmental Protection Agency (EPA) is directed by the Safe Drinking Water 

Act (SDWA) to annually report on public water system (PWS) compliance in the United States. To meet 

this requirement, EPA’s Office of Enforcement and Compliance Assurance (OECA) publishes the annual 

National Public Water Systems Compliance Report (Report) summarizing the incidence of significant 

violations, which include all health-based violations and a subset of other violations, as shown in Table 

A-1. The Report for 2012 documents that, while the majority of the U.S. population served by PWSs

receives safe drinking water, many PWSs incurred significant violations of federal drinking water quality 

standards. The number of PWSs with significant violations decreased from 37,631 in 2011 to 36,536 in 

2012.

By the end of December 2012, there were 150,848 active1 PWSs in the U.S., serving over 320 million 

consumers. Small PWSs2 comprise the vast majority of all these systems. Noncompliance occurs more 

frequently at smaller PWSs because they often have fewer resources to operate and maintain compliance.

For this reason, EPA, states, and other organizations provide significant assistance and resources to small

PWSs to build their capacity to properly finance, operate, and maintain their drinking water systems.

Among other mechanisms to support small PWSs, EPA provides funds through the Drinking Water State 

Revolving Fund and the Public Water System Supervision (PWSS) program for third-party technical 

assistance providers, and maintains multiple, free online financial and technical web sites, tools and 

resources.

Overall Compliance Is Improving

EPA tracks compliance at PWSs in different ways and for different purposes. For purposes of this report, 

EPA tracks compliance in two ways: 1) the number of PWSs with significant violations3 reported to EPA 

by primacy agencies each year (that is, any health-based violation or certain monitoring and reporting 

violations where the facility fails to report water sampling results); and 2) the number of PWSs classified 

as being priorities for enforcement (that is, they have serious, repeated or continuing violations that make 

them a priority, as defined by the 2009 SDWA Enforcement Response Policy).

The number of PWSs with significant violations (i.e., health-based, certain monitoring and reporting, or 

certain notification violations) reported to EPA each year decreased incrementally between 2008 and 

2012. The most frequently reported violations continue to be monitoring and reporting violations. Failure 

to monitor or report is serious because it means that regulators and consumers do not know whether 

drinking water standards are being met.

1 For purposes of this report, active PWSs are defined as those PWSs that have operated for some period in the 

calendar year. This would include PWSs that are only operating during part of the year, such as summer 

campgrounds. Any system reported by its primacy agency to be permanently closed by December 31, 2012 is not 

included in this report; neither are its violations. In other reportings, such as for the Government Performance and 

Reports Act (GPRA), active PWSs are defined differently.

2 Small systems are defined in some contexts as serving 3,300 or fewer customers, and in others as serving 10,000 or 

fewer. For purposes of this report, references to small systems always refer to those serving 3,300 or fewer. In other 

EPA documents, small systems may be further categorized into very small systems as those serving 500 or fewer 

customers.

3 Details concerning significant violations can be found in Appendix A in Table A-1. 

1

 
Beginning in 2010, EPA established a water system-based approach4 to addressing noncompliance with 

federal requirements in accordance with the revised Enforcement Response Policy (ERP) issued on 

December 8, 2009. This policy instituted a process for prioritizing systems for enforcement based on the 

number and types of violations at each system. Using this approach, all violations at a priority system are

to be addressed through a consolidated response by the primacy agency. For more information on the 

2009 ERP, see 

http://www.epa.gov/compliance/resources/policies/civil/sdwa/drinking_water_erp_2009.pdf.

The number of PWSs classified as priorities for enforcement at some time during the calendar year

decreased from 8,172 (5 percent of all systems) in 2011 to 6,352 (4 percent) in 2012. Primacy agencies 

made progress in addressing a backlog of noncompliance through compliance assistance and enforcement 

actions, while reporting those activities into the national data system.

Compliance and Enforcement at PWSs in the U.S., Including Indian Country5

Primacy agencies6 reported that approximately 24 percent of all PWSs in the U.S. had at least one 

significant violation in 2012. This rate is slightly lower than the rates reported in previous years. The data 

submitted by primacy agencies indicate that 6 percent of all PWSs in the U.S. serving approximately 23.7 

million consumers had violations of health-based standards in 2012, while significant monitoring and 

reporting violations were reported for about 15 percent of all PWSs. In 2012, EPA and primacy agencies 

initiated 7,809 enforcement actions7 in response to drinking water violations at PWSs in their 

jurisdictions. The enforcement actions counted in this report are a subset of all possible enforcement 

actions, which include formal enforcement actions and other, more informal actions that may return a 

system to compliance.

Compliance and Enforcement at PWSs in Indian Country 

In 2012, 985 PWSs served almost 1.3 million consumers in Indian country. EPA and the Navajo Nation 

reported that approximately 49 percent of all PWSs in Indian country had at least one significant violation 

in 2012. The rate is higher than the violation rate of 42 percent reported in 2011. The Indian country data 

indicate that 12 percent of PWSs in Indian country, serving approximately 243,723 consumers, had 

violations of health-based standards in 2012, which is higher than the 11 percent reported last year. In 

2012, significant monitoring and reporting violations were reported for 42 percent of PWSs in Indian 

4 The previous approach prioritized systems for enforcement based on the violations under each regulation 

separately. With the increased number of regulations developed over time the water system approach is more 

efficient.

5 Indian Country means (a) all land within the limits of any Indian reservation under the jurisdiction of the United 

States Government, notwithstanding the issuance of any patent, and, including rights-of-way running through the 

reservation, (b) all dependent Indian communities within the borders of the United States whether within the original 

or subsequently acquired territory thereof, and whether within or without the limits of a state, and (c) all Indian 

allotments, the Indian titles to which have not been extinguished, including rights-of-way running through the same. 6 Federal approval to implement the drinking water program is called primary enforcement authority, or “primacy.” 

The term “primacy agency” includes 54 states, commonwealths, and territories that have been approved to 

implement the drinking water program within their jurisdictions. It also includes the Navajo Nation, which has 

primacy for most, but not all, PWSs that are located on Navajo lands. When this report mentions PWSs in the 

Navajo Nation, it refers to those PWSs for which the Navajo Nation exercises primacy. During calendar year 2012, 

EPA directly implemented the drinking water program in Wyoming, the District of Columbia, and throughout all of 

Indian country, except for those PWSs under Navajo Nation primacy. EPA is responsible for submitting violation 

information into Safe Drinking Water Information System (SDWIS) for the areas where the Agency directly 

implements the program.

7 For purposes of this report, enforcement actions include a variety of administrative, civil and criminal actions, and 

other actions that primacy agencies use to address violations.

country, which is higher than the rate of 34 percent reported in 2011. The increase was mainly due to the 

consistent application of the protocol implementing offices use to determine if a PWS has complied with 

monitoring and reporting requirements. In 2012, EPA and the Navajo Nation took 46 enforcement actions 

in Indian country.

The PWSs in Indian country consist mainly of smaller PWSs, many of which may face significant 

financial and technical challenges in complying with National Primary Drinking Water Regulations 

(NPDWRs). EPA devotes considerable financial and staff resources to improve compliance in Indian 

country, as discussed in more detail in this report.

Source and Quality of Data Used for this Report

The data summarized in this report are stored in the Safe Drinking Water Information System/Federal 

Version (SDWIS/FED). PWSs are required to sample and test their water and report the results to the 

agency with primacy for implementing the SDWA. The primacy agency reviews the test results and other 

required reports and determines whether a violation has occurred. The primacy agency is required by EPA 

to report all violations and enforcement data into SDWIS/FED; a finding of compliance is not required to 

be reported to EPA.

EPA has evaluated state and regional programs’ data quality by conducting data verification audits and 

national data quality assessments, comparing primacy agencies’ files and records with information in 

SDWIS/FED to verify accuracy, completeness and whether appropriate compliance determinations are 

made (that is, in accordance with federal regulations). These audits and assessments have shown that 

violation data are substantially incomplete. EPA and primacy agencies are currently working together to 

devise a modern data system that will be instrumental in improving data accuracy and completeness. EPA 

is developing a methodology for evaluating the quality of the enforcement data and hopes to begin 

deploying it in future years, as resources allow.

Recommendations

1. Continue to Improve Compliance Rates

States, territories, the Navajo Nation, and EPA should continue working together to return violating 

PWSs to compliance as efficiently and effectively as possible. Pursuing the more holistic, systems-based 

approach to addressing noncompliance is an important element of improving performance among PWSs.

EPA needs to aggressively push compliance in states that have large number of their public water systems 

classified as enforcement priorities.

2. Improve Data Quality

Data quality improvement must remain a high priority for EPA and the primacy agencies. Primacy 

agencies must provide complete and accurate data to the public and to EPA. Without high quality data 

from primacy agencies, EPA cannot fulfill its responsibility to fully assess the state of compliance of the 

nation’s PWSs and to communicate to the public, Congress and other oversight bodies.

3. Continue to Implement the 2009 Enforcement Response Policy

Primacy agencies will continue to pursue enforcement actions against violating public water systems both 

to expeditiously return violations to compliance and to deter future violations. EPA and primacy agencies 

will continue to implement the ERP and provide training and support as needed.

3
4. Continue to Develop Capacity at Smaller Public Water Systems

EPA will continue its efforts to support PWSs serving 10,000 or fewer consumers through the capacity 

development program. Recognizing the challenges facing these drinking water systems, EPA provides 

tools and assistance for capacity development, which refers to the technical, financial and managerial 

capacity of a system to provide safe drinking water. The program also provides information about 

treatment technology options for small systems.

5. Continue to Increase Transparency of Data

EPA believes that raising the public’s awareness of the violations at PWSs will encourage PWSs to 

improve their compliance. In addition to the information in this report, data on the numbers and types of 

PWSs, populations served, source water, violations, enforcement actions and more are presented in 

various other formats on EPA’s public web site at the following URLs:

Readers should be aware that data in these reports and others using SDWIS data may differ somewhat, 

depending on the specific queries and dates of information used to generate each report.

2012 National Public Water Systems Compliance Report

Introduction

Purpose of Report

This annual National Public Water Systems Compliance Report summarizes and evaluates annual reports 

submitted by primacy agencies regarding compliance at public water systems (PWSs) of all types and 

sizes in the U.S. in calendar year 2012. The information in this report summarizes PWS noncompliance 

with the National Primary Drinking Water Regulations (NPDWRs) at the national and state levels and 

does not provide information about specific water systems. This report is compiled annually as required 

by Section 1414(c)(3)(B) of the Safe Drinking Water Act (SDWA). The report includes the following:

 Part 1: Summary of Compliance and Enforcement at PWSs throughout the U.S (including those in 

Indian Country)

 Part 2: Summary of Compliance, Enforcement, and Financial Assistance at PWSs in Indian Country

 Part 3: Conclusions and Recommendations

 Appendices: Glossary of Terms and Summaries of Primacy Agency Reports 

Scope of Report

This report discusses the incidence of significant violations, as defined by the SDWA and shown in Table 

A-1, at PWSs that occurred between January 1 and December 31, 2012, including:

 All violations of health-based standards, including exceedances of Maximum Contaminant Levels 

(MCLs), Maximum Residual Disinfectant Levels (MRDLs) and violations of treatment technique

(TT) requirements;

 Significant notification violations (i.e., complete failure to provide required notification); and

 Significant monitoring and reporting violations (e.g., where a PWS did not take a sample or failed 

to report results during a compliance period).

A PWS is a system that provides water for human consumption, if such system has at least 15 service 

connections or regularly serves at least 25 individuals at least 60 days out of the year. EPA does not have 

the authority to regulate private drinking water wells that do not meet the above criteria. Therefore, data 

in this report are for PWSs only.

For purposes of this report, EPA defines small systems as those serving up to 3,300 customers. PWS size 

is generally associated with a system’s ability to maintain or return to compliance following a violation of 

a NPDWR. In general, large PWSs have greater capacity to maintain compliance than small systems and 

can return to compliance more quickly than small systems. This disparity is often the result of differences 

in financial, administrative, and technical capacity between large and small systems. Small PWSs have a 

smaller customer base to support purchase and installation of needed infrastructure and to operate and 

maintain the system. Similarly, small PWSs may be unable or unwilling to charge consumers rates 

sufficient to cover the true cost of collecting, treating, and distributing the water. Lack of funding may 

cause small PWSs to delay needed capital improvements. Small PWSs (particularly non-community 

water systems) are often overseen by part-time administrators who are not environmental professionals, 

and the pay for the system operators may not be adequate to attract and keep someone with the necessary 

training and skills. If there are violations, small PWSs may not have the technical capabilities to correct 

the underlying problems. Because of the relationship between system size and the ability to achieve and 

maintain compliance, some of the findings in this report are discussed in terms of system size.

5
EPA’s goal is to ensure that all citizens are provided with safe drinking water. The Enforcement Response 

Policy (ERP) for the Public Water System Supervision (PWSS) Program under the SDWA issued on 

December 8, 2009, reiterates that formal enforcement action should be taken when assistance or informal 

enforcement action does not effectively return a PWS to compliance in a timely manner, regardless of the 

size, type, owner, operator or location of the system. The ERP establishes a framework for prioritizing 

PWSs for formal enforcement in order to ensure that those with the most severe violations are addressed.

Systems with the most serious violations or combination of frequent or persistent violations are 

considered to be priorities for enforcement. When determining if a PWS is an enforcement priority, the 

ERP considers all unresolved violations within the past five years. The ERP expects that all violations at a 

PWS must be corrected or addressed, thus returning the PWS to compliance more quickly than was 

previously done. This practice began in 2006 on an ad-hoc basis and triggered a decline in the number of 

PWSs prioritized for enforcement. With the inclusion of this provision in the 2009 ERP, EPA expects this 

decline to continue. Data for 2012 confirm this expectation. 

Source and Quality of Data

This report is based on violation types shown in Table A-1 (Appendix A) that occurred during calendar 

year 2012. EPA acknowledges that the data summarized in this report are incomplete. The data are 

housed in the Safe Drinking Water Information System/Federal Version (SDWIS/FED). PWSs are 

required to take samples and test their water and report the results to their primacy agency—usually the 

state in which the system is located, or to EPA if the system is in Wyoming, the District of Columbia, or 

Indian country where a tribe does not have primacy. The primacy agency reviews the test results and 

other required reports and determines whether a violation has occurred. The primacy agency is required 

by EPA to enter all violation and enforcement data into SDWIS/FED; a finding of compliance is not 

required to be entered into SDWIS/FED.

EPA has evaluated state and EPA regional programs’ data quality by conducting data verification audits 

and national data quality assessments, comparing primacy agencies’ files and records with information in 

SDWIS/FED to verify accuracy, completeness and whether appropriate compliance determinations are 

made (that is, in accordance with federal regulations). These audits and assessments have shown that 

violation data are substantially incomplete. EPA and primacy agencies are currently working together to 

devise a modern data system that will be instrumental in improving data accuracy and completeness. 

EPA is developing a methodology for evaluating the quality of the enforcement data and hopes to begin 

deploying it in future years, as resources allow.

Part 1. Summary of Compliance and Enforcement at Public Water 

Systems throughout the U.S. (Including Those in Indian Country)

Inventory of Public Water Systems by Size

The number of active PWSs8 operating in 2012 was 150,848, serving over 320 million consumers. The 

proportion of small PWSs to the total number of PWSs remained consistent with previous years at 94

percent.

 

Small PWSs comprise the vast majority of all PWSs, but they serve just 12 percent of all consumers. For 

this report, EPA defines small PWSs as those serving 3,300 or fewer customers. For discussion purposes, 

systems serving more than 3,300 customers (i.e., medium, large, and very large systems) are grouped 

together throughout this report. Small PWSs include both community water systems (those systems that 

serve the same individuals year-round), as well as non-community systems serving at least 25 people for 

at least 60 days per year. PWSs can be divided into community and non-community water systems. Some 

examples of non-community systems include offices, schools, hospitals, gas stations and parks with their 

own water supply.

 

PWSs with Significant Violations of Any Type

In 2012, about 76 percent (114,492) of PWSs in the U.S., serving approximately 82 percent of the 

population, had no significant violation of any type, as reported by primacy agencies9

. Significant 

violations include all violations of health-based standards, including exceedances of MCLs and MRDLs

and violations of TT rules; certain notification violations (i.e., complete failure to provide required 

8 For purposes of this report, active PWSs are defined as those PWSs that have operated for some period in the 

calendar year. This would include PWSs that are only operating during part of the year, such as summer 

campgrounds. Any system reported by its primacy agency to be permanently closed by December 31, 2012 is not 

included in this report; neither are its violations. In other reportings, such as for the Government Performance and 

Reports Act (GPRA), active PWSs are defined differently. 9 All references to populations served throughout this report are approximate, because most receive drinking water 

from more than one system (e.g., at home, at work, at parks or at commercial establishments, etc.). Therefore, 

adding the number of consumers of all system types would result in a number greater than the entire U.S. 

population.

notification); and certain monitoring and reporting violations (failure to sample or to report results during 

a compliance period). Significant violations were reported for 36,356 PWSs in 2012, representing about 

24 percent of all active PWSs. This rate shows a slight decrease between 2008 and 2012. 

More than 60 percent of all significant violations reported were monitoring and reporting violations. The 

graph below shows that the greatest number of PWSs had violations of this type. Note that the total of the 

numbers of systems in the graph below is greater than the 36,356 PWSs with significant violations of at 

least one NPDWR, because some systems had significant violations of multiple NPDWRs.

PWSs with Health-Based Violations

Based on data reported by primacy agencies, 94 percent of PWSs (142,182) had no reported violations of 

health-based standards. Conversely, 6 percent of PWSs (8,666) did have reported health-based violations. 

These PWSs with reported health-based violations served approximately 23.7 million consumers in 2012.

EPA’s health-based standards are designed to protect human health by preventing the occurrence of 

unsafe levels of contaminants in drinking water. Health-based standards include MCLs, MRDLs, and 

TTs. An MCL is the highest level of a contaminant that is allowed in drinking water. An MRDL is the 

highest level of a disinfectant residual that is allowed in the drinking water. A TT is a required treatment 

process (such as filtration or disinfection) intended to prevent the occurrence of or deactivate a 

contaminant in drinking water. TTs are adopted where it is not economically or technologically feasible 

to monitor the level of a contaminant, such as microbes, where even single organisms that occur 

unpredictably or episodically can cause adverse health effects.

It is important to note that when a PWS violates a health-based standard, the consumers served by that 

system may be at an increased risk of illness depending upon several factors, including the type and 

concentration of the contaminant and the duration and the magnitude of the exceedance. PWSs that 

exceed MCLs or MRDLs or fail to meet minimum TT requirements are required to notify their consumers 

about the possibility of these increased health risks.

Public Water Systems with Significant Monitoring and Reporting Violations

If a system does not monitor the quality of its water, it is impossible for consumers and primacy agencies 

to know whether the water being served is meeting health-based standards. For this reason, a system’s 

failure to monitor and report for an entire compliance period is a significant violation that must be 

addressed and corrected. In 2012, primacy agencies reported significant monitoring and reporting 

violations for about 15 percent of all PWSs (23,091). Approximately 56 percent of the 23,091 PWSs in 

2012 had at least one violation of monitoring and reporting requirements of the Total Coliform Rule

(TCR). Unlike the other NPDWRs (except for nitrate/nitrite, which is similar to TCR), the TCR applies to 

all PWSs with many PWSs monitoring multiple times per year, thus increasing the likelihood of the 

primacy agency reporting a TCR violation. 

Violations Reported Most Frequently

In 2012, primacy agencies reported 14,739 health-based violations at 8,666 PWSs as well as 77,554

significant monitoring and reporting violations at 23,091 PWSs. Monitoring and reporting (M/R) 

violations for the Chemical Contaminant Group were the most frequent M/R violations, at 54 percent. 

The higher frequency of M/R violations for the Chemical Contaminant Group is likely because a single 

monitoring sample may be used for various inorganic and organic contaminants. Compliance with many 

organic and inorganic standards is determined on the basis of a sample being analyzed for multiple 

contaminants, with one missed sample resulting in M/R violations for each of those contaminant 

standards. 

The following graph shows the rates at which significant violations were reported to have occurred in 

2012, by rule. The rules or rule categories in the graph include:

 Chem -- Chemical Contaminant Group. This category includes rules for synthetic organic, volatile 

organic, inorganic (except for lead and copper), and radioactive contaminants. 

 TCR -- Total Coliform Rule

 LCR -- Lead and Copper Rule

9
 SWR (Surface Water Rules) -- This category includes the long-term 1 enhanced surface water 

treatment rule (LT1ESWTR), long-term 2 enhanced surface water treatment rule (LT2ESWTR), 

surface water treatment rule (SWTR), interim enhanced surface water rule (IESWTR) and filter 

backwash recycling rule (FBRR).

 DBPR -- Stage 1 Disinfectants and Disinfection Byproducts Rule and Stage 2 Disinfectants and 

Disinfection Byproduct Rule

 GWR - Ground Water Rule.

As context for the total number of violations occurring in a year, it is important to note that PWSs are 

subject to numerous rules and standards, depending on their size, type, and source of water. A large 

system may be required to sample as many as 480 times in one month under the TCR, with the potential 

for 5,760 health-based violations in a year for that rule at that one system. A small PWS may be required 

to sample just once a month under the same rule. Similarly, failure to take one required sample that is 

used to test for multiple contaminants results in separate monitoring and reporting violations for each 

contaminant tested for in the sample. 

PWSs with Violations of Variances or Exemptions

Under federal law, EPA and primacy agencies can grant variances or exemptions to PWSs in limited 

circumstances allowing them to install alternative technology or giving them more time to meet a 

standard if public health is adequately protected in the interim. Five violations of variances or 

exemptions were reported by primacy agencies during 2012. 

Primacy Agencies and EPA Response to Violations

Assistance 

State primacy agencies and EPA engage in a variety of compliance, financial and technical assistance 

activities to help PWSs remain in and/or return to compliance. These activities are often general and 

ongoing, while others are targeted to specific systems or NPDWRs. Examples include:

 Conducting on-site visits and sanitary surveys at PWSs (e.g., an on-site review of the water sources,

 Helping PWSs identify and implement preventive measures;

 Providing financial assistance for system improvements through the Drinking Water State Revolving 

Fund;

 Reviewing water system plans and specifications;

 Conducting training sessions;

 Holding public information meetings;

 Lending specialized monitoring equipment, such as handheld equipment; and

 Publishing information and providing training events and other educational opportunities.

PWSs often return to compliance on their own without assistance or other primacy agency response.

Informal Enforcement

When a drinking water violation is identified and a PWS does not resolve its violation on its own, or 

compliance assistance does not return the violating system to compliance, EPA program implementation 

guidelines direct the primacy agency to initiate an enforcement response. Generally, the primacy 

agency’s first response to violations are informal actions such as field visits, reminder letters, telephone 

calls, warning letters, and notices of violation. 

Formal Enforcement

If a violation continues or recurs, the primacy agency must initiate a formal enforcement response that 

requires the violating PWS to return to compliance under an enforceable timetable. Formal enforcement 

responses include citations, administrative orders with or without penalties, civil referrals to state or 

Navajo Nation attorneys general, or the U.S. Department of Justice, filing criminal charges, and other 

sanctions. The timetable establishes when a PWS must have taken all corrective actions needed to return 

to compliance. This may be years, particularly when new construction and/or equipment are needed to 

return a PWS to compliance. If there is a risk to public health, EPA and those entities with primacy, 

including the Navajo Nation, can issue emergency orders that require the PWS to immediately take action 

to protect public health and return the system to compliance. 

Prioritization of Systems for Enforcement

In 2010, EPA and primacy agencies began implementing a revised ERP, which changed the prioritization 

process to one that is more protective of public health. The policy lays out expectations for timely and 

appropriate enforcement response. All unresolved violations not already under formal enforcement at 

each PWS are considered in the prioritization process. PWSs are then ranked according to the seriousness

of their violations, with acute health-based violations weighted most heavily. This ranking allows 

primacy agencies to distinguish the systems with the most serious noncompliance and to allocate 

enforcement resources accordingly. More detail about the prioritization and expectations for primacy 

agencies can be found in the ERP on EPA’s web site at 

http://www.epa.gov/compliance/resources/policies/civil/sdwa/drinking_water_erp_2009.pdf.

A decrease in the number of PWSs classified as priorities for enforcement was seen from 2011 (8,172) to 

2012 (6,352). About 4 percent of all PWSs were enforcement priorities at least once during 2012. This is 

down from 5 percent of all PWSs in 2011. Approximately 2-3 percent of all PWSs were enforcement 

priorities in any given quarter, as primacy agencies implemented the ERP.

11
In 2012, EPA and primacy agencies initiated 7,809 enforcement actions10 in response to drinking water 

violations at PWSs in their jurisdictions. The enforcement actions counted in this report are a subset of 

all possible enforcement actions, which include some formal enforcement actions and other actions that 

may return a system to compliance. Generally, the primacy agency’s first response to violations are 

informal actions such as reminder letters, warning letters, notices of violation, field visits, and telephone 

calls. In 2012, primacy agencies initiated 96,081 informal enforcement actions. The vast majority of these 

actions were taken by primacy states. EPA has primacy in Wyoming, the District of Columbia, and in 

Indian country, except for the Navajo Nation. EPA’s actions were primarily in these areas where it has 

primacy. EPA also initiates enforcement action in primacy states, often at a state’s invitation.

It is important to note that the number of enforcement actions in a year does not necessarily correlate with 

the violations that are reported in the same year. Most violations are resolved without the need for 

enforcement action of any kind. Many enforcement actions are initiated against violations that occurred 

in a previous year. One enforcement action may address numerous violations at the same system. It is 

also important to note that it may take several years for a system to return to full compliance once an 

enforcement action is initiated, such as when new treatment technology must be financed, procured, 

installed and brought online.

10 For purposes of this report, enforcement actions include a variety of administrative, civil and criminal actions, and 

other actions that primacy agencies use to address violations.

Part 2. Summary of Compliance, Enforcement, and Financial 

Assistance at Public Water Systems in Indian Country

Implementation of SDWA in Indian Country

This section of the report provides information for PWSs in Indian country where EPA has primacy and 

most PWSs in the Navajo Nation.

11 The data exclude PWSs in the Navajo Nation that are not under 

Navajo Primacy and PWSs in Alaskan Native Villages. The state of Alaska is the primacy agency with 

oversight of PWSs for Alaska Native Villages. The data also exclude eighteen PWSs serving Native 

Americans that are located in Oklahoma, as EPA is reviewing the designation of the land in which they 

are located. Information on these facilities is incorporated in the state reports for Alaska and Oklahoma.12 

Inventory of PWSs by Size in Indian Country

In 2012, 985 PWSs served almost 1.3 million consumers in Indian country. Small PWSs comprised 91 

percent of all PWSs in Indian country serving approximately 41 percent of the people who received water 

from PWSs. This is in contrast to the U.S. as a whole where small PWSs comprise 94 percent of all 

PWSs and serve approximately 12 percent of all consumers. The percentage of small PWSs in Indian 

country with violations is greater than the percentage of small PWSs outside of Indian country with 

violations. 

 

PWSs with Significant Violations of Any Type in Indian Country

In 2012, EPA and the Navajo Nation reported that 51 percent or 503 of the 985 PWSs in Indian country

for which they have primacy, serving approximately 739,653 consumers, had no significant violation of 

any type. Conversely, 49 percent of PWSs had at least one significant violation reported, more than twice 

the rate outside of Indian country (24 percent). The rate has been declining over the period for which 

trends were calculated. Fluctuation from one year to the next occurs due to the large number of systems 

and potential violations. In addition, fluctuation may be due to the cyclical nature of the chemical 

11 Federally-recognized Indian tribes may apply for primacy to administer the drinking water program provided they 

meet the requirements of Sections 1413 and 1451 of the SDWA. Only the Navajo Nation had sought and received 

primacy for most PWSs on the Navajo Reservation. EPA administers the drinking water program in the rest of 

Indian country.

12 Alaska and Oklahoma do not separate tribal information from non-tribal information in their state reports.

contaminant group monitoring requirements, which are on a three to nine-year schedule. The chemical 

contaminant group consists of over seventy contaminants. To reduce the complexity of monitoring, EPA 

developed the standardized monitoring framework outlining monitoring schedules covering three to nine 

year periods. While the general decline in this rate since 2008 is important, EPA considers this percentage

of significant violations to be too high and that further actions are necessary to improve noncompliance.

The types of violations reported by the 482 PWSs (49 percent) are shown below. Significant monitoring 

and reporting violations comprise the most frequently reported violations of all types in Indian country

and outside of Indian country.

Note that the total number of PWSs in the graph is less than the 482 PWSs that violated at least one 

NPDWR because some systems violated multiple NPDWRs.

PWSs with Health-Based Violations in Indian Country

In Indian country 12 percent of PWSs (121 systems) had health-based violations in 2012. These PWSs

served 19 percent (243,723) of consumers in 2012.

PWSs with Significant Monitoring and Reporting Violations in Indian Country

If a PWS does not monitor the quality of its water, it is impossible to know if drinking water standards are 

being met. For this reason, a significant failure to monitor and report is a major violation that must be 

addressed and corrected. Overall, the most frequently reported violations are significant monitoring and 

reporting violations, both inside Indian country and outside. In 2012, 42 percent of PWSs (418 systems)

in Indian country had significant monitoring and reporting violations, which is 8 percent higher and 85 

more systems than the rate of 34 percent reported in 2011. This increase followed a review of how 

implementing offices apply the protocols used to determine if a PWS has complied with monitoring and 

reporting requirements. More consistent application of these protocols in 2012 resulted in more systems 

being found in violation of significant monitoring and reporting requirements in that year than in 2011. 

Violations Reported Most Frequently in Indian Country

The most frequently reported contaminant-related violation among all PWSs in Indian country was

monitoring and reporting under the Chemical Contaminant Group (63 percent). Exceedances of the MCL 

for the Chemical Contaminant Group were the most frequently reported health-based violations, making 

up 45 percent of all health-based violations.

No violations of variances or exemptions were reported by the primacy agencies for Indian country 

during 2012. 

EPA Response to Violations in Indian Country

In 2012, EPA devoted significant financial and staff resources to improve compliance in Indian country.

The PWSs in Indian country consist mainly of smaller PWSs that face significant financial and technical 

challenges in complying with NPDWRs.

Assistance for PWSs in Indian Country

EPA engages in a variety of compliance, financial and technical assistance activities to help PWSs for 

which they have primacy remain in and/or return to compliance. These activities are often generic and 

ongoing, while others are targeted to specific PWSs. Examples include:

 Conducting on-site visits and sanitary surveys at PWSs (e.g., an on-site review of the water sources, 

facilities, equipment, operations, and maintenance to evaluate their adequacy in producing and 

distributing safe drinking water); sanitary surveys are required to be conducted at community water 

systems every three years and at non-community water systems every five years.

 Helping PWSs identify and implement preventive measures;

 Providing financial assistance for system improvements through the Drinking Water Infrastructure 

Tribal Set-Aside program;

 Conducting training sessions;

 Holding public information meetings;

 Lending specialized monitoring equipment, such as handheld equipment; and

 Publishing information and providing training events and other educational opportunities.

In many cases, EPA coordinates its assistance with other federal agencies, including the U.S. Department 

of Health and Human Service’s Indian Health Service, the U.S. Department of Agriculture’s Rural

Utilities Service, and the Department of the Interior’s Bureau of Indian Affairs and Bureau of 

Reclamation. In addition, EPA works with non-governmental organizations and inter-tribal consortia, 

including the Native American Water Association, the National Rural Water Association, and the Rural 

Community Assistance Partnership to ensure compliance at PWSs in Indian country.

PWSs often return to compliance on their own without assistance or other EPA and non-EPA responses.

Informal Enforcement for Violations in Indian Country

When a drinking water violation is identified and a PWS does not resolve its violation on its own, or 

compliance assistance does not return the violating system to compliance, EPA’s program 

implementation guidelines direct the primacy agency to initiate an enforcement response. Generally, 

EPA or the Navajo Nation’s first response to violations are informal actions such as field visits, reminder 

letters, telephone calls, warning letters, and notices of violation. If a PWS is owned or operated by a tribal 

government, EPA’s enforcement response is guided both by the SDWA and program implementation 

guidance and the “EPA Policy for the Administration of Environmental Programs on Indian 

Reservations” and the “Guidance on the Enforcement Principles Outlined in the 1984 Indian Policy”

(EPA Enforcement Principles). For more information, see http://www2.epa.gov/enforcement/transmittal-finalguidance-enforcement-principles-outlined-1984-indian-policy-january-17 and http://www.epa.gov/tp/pdf/indianpolicy-84.pdf.

Formal Enforcement for Violations in Indian Country

If a violation continues or recurs, the primacy agency must initiate a formal enforcement response that 

requires the violating PWS to return to compliance under an enforceable timetable. Formal enforcement 

responses include citations, administrative orders with or without penalties, civil referrals to state or 

Navajo Nation attorneys general, or to the U.S. Department of Justice, filing criminal charges, and other 

sanctions. The timetable establishes when a PWS must have taken all corrective actions needed to return 

to compliance. This may be years, particularly when new construction and/or equipment are needed to 

return a PWS to compliance. If there is risk to public health, EPA can issue emergency orders that 

require the PWS to immediately take action to protect public health and return the system to compliance.

In 2012, EPA and the Navajo Nation took 46 enforcement actions in Indian country.

Prioritization of PWSs in Indian Country for Enforcement13

Beginning in 2010, EPA and the Navajo Nation began implementing the revised ERP in Indian country, 

which changed the prioritization process to one that is more protective of public health. The policy also 

lays out expectations for timely and appropriate enforcement response. All unresolved violations at each 

PWS are considered in the prioritization process. Acute health-based violations are weighted most 

heavily in the prioritization. All PWSs are ranked according to the severity of their unresolved violations. 

This ranking allows primacy agencies to distinguish the PWSs with the most serious noncompliance and 

to allocate enforcement resources accordingly. The ERP can be found on EPA’s web site at 

http://www.epa.gov/compliance/resources/policies/civil/sdwa/drinking_water_erp_2009.pdf.

The ERP is applied to all PWSs in the U.S. and its territories. If a PWS is owned or operated by a tribal 

government, EPA’s informal and formal enforcement responses are guided both by the SDWA and 

program implementation guidance and the “EPA Policy for the Administration of Environmental 

13 Enforcement actions counted in this report include a variety of administrative, civil and criminal actions, and other 

actions that primacy agencies use to address violations.

17

 
Programs on Indian Reservations” and the “Guidance on the Enforcement Principles Outlined in the 1984 

Indian Policy.”

About 14 percent (139 PWSs) of all PWSs in Indian country were priorities for enforcement at least once 

during 2012. This is down from 19 percent (185 PWSs) in 2011. Approximately four to ten percent of all 

systems in Indian country were priorities for enforcement in any given quarter. These rates are more than 

twice of those at PWSs in the U.S. as a whole.

It is important to note that the number of enforcement actions in a year does not necessarily correlate with 

the violations that are reported in the same year. Most violations are resolved without the need for 

enforcement action of any kind. Many enforcement actions are initiated against violations that occurred 

in a previous year. One enforcement action may address numerous violations at the same PWS. It is 

also important to note that it may take several years for PWSs to return to full compliance once 

enforcement actions are initiated, such as when new treatment technologies must be financed, procured, 

installed and brought online.

Financial Assistance for PWSs in Indian Country

EPA provides financial assistance to tribes to help build water system infrastructure and improve 

compliance with SDWA requirements. 

From the national PWSS program’s allotment for FY2012, EPA set aside $6,779,000 for activities in 

Indian country. These funds are available to support tribes that have received primacy (currently only the 

Navajo Nation), assist tribes with the development of primacy programs and individual components of 

PWSS programs, and support direct implementation activities in Indian country where EPA is the 

primacy agency. These funds are used for activities such as:

 Providing technical assistance to owners and operators of water systems; 

 Maintaining compliance data systems; 

 Compiling and analyzing compliance information; 

 Responding to violations; and

 Conducting sanitary surveys.

EPA distributes funds to improve the infrastructure of PWSs to achieve compliance. Each year, two

percent of the appropriation for the national Drinking Water State Revolving Fund program is set aside 

for American Indian communities and Alaska Native Villages. The FY 2012 set-aside amounted to 

$18,358,000. These funds are used for the following:

 Distribution and transmission system improvements;

 Community water system extensions;

 Storage facilities;

 Treatment improvements; and

 Construction of new pump houses.

18
Part 3. Conclusions and Recommendations

Compliance and Enforcement at U.S. Public Water Systems

The data reported by primacy agencies indicate that 76 percent of PWSs in the U.S. had no significant 

violation of any type. Conversely, 24 percent of PWSs did have at least one significant violation. That 

rate was slightly less than 25 percent of PWSs in 2011. 

The data reported by primacy agencies indicate that 6 percent of PWSs, serving about 23.7 million 

consumers, had violations of health-based standards in 2012. EPA believes that these rates are too high 

and that additional efforts are necessary to improve compliance.

In 2012, about 23,091, or 15 percent, of all PWSs had significant monitoring and reporting violations. 

This rate did not change from 2011. Failure to monitor and report prevents systems and consumers from 

knowing whether drinking water standards are being met.

There was a decrease in the percentage of PWSs that were classified as priority systems for enforcement 

under the SDWA ERP from five percent in 2011 to four percent in 2012.

Compliance and Enforcement at Public Water Systems in Indian Country 

In 2012, primacy agencies reported that 49 percent of PWSs (482 systems) in Indian country had a 

significant violation of some type. This rate has generally been declining since 2008, ranging from 63-42

percent. 

EPA regions and Navajo Nations reported that 12percent of the PWSs in Indian country had health-based 

violations and 42 percent had significant monitoring and reporting violations in 2012. This is of concern 

because if a system does not monitor and report on the quality of its water, it is impossible to know if 

health-based standards are being met. EPA is working to address these rates through effectively 

implementing the 2009 ERP and OECA‘s Guidance on the Enforcement Principles Outlined in the 1984 

Indian Policy. Consultation with tribes, civil inspections and enforcement activity are aimed to ensure the 

same degree of protection of human health and environmental protection in Indian country as elsewhere 

in the U.S. About 14 percent of all PWSs in Indian country were enforcement priorities at least once 

during 2012. Approximately four to ten percent of all systems in Indian country were enforcement 

priorities in any given quarter.

Conclusions

The rate at which significant violations occur, according to data provided by primacy agencies, have 

shown a decrease from 2011 and generally over the five years for which trends were calculated. Since 

implementing the ERP in 2010, the number of PWSs classified as enforcement priorities decreased from

nine percent to four percent of all PWSs. This decrease reflects efforts on the part of EPA and states to 

provide assistance and other informal means to prevent noncompliance, address data quality issues,

address violations in a timely manner, and return violating PWSs to compliance as expeditiously as 

possible. Nevertheless, EPA believes that violation rates are still too high and that additional efforts are 

necessary to improve compliance. 

EPA recognizes that there are higher rates of significant noncompliance in drinking water systems in 

Indian country than those outside of Indian country. EPA is increasing its efforts to prevent and address 

noncompliance in Indian country in an effort to reduce the disparity. 

19
Compliance statistics are based on violations reported by primacy agencies to SDWIS/FED. EPA is 

aware of inaccuracies and underreporting of some data in this system. EPA is working with primacy 

agencies and internally to improve the quality of the data.

Recommendations

1. Continue to Improve Compliance 

States, territories, Navajo Nation, and EPA should continue working together and with the regulated 

entities to return violating systems to compliance, as efficiently and effectively as possible. Pursuing the 

more holistic, systems-based approach to addressing noncompliance in all primacy agencies is an 

important element of improving performance among PWSs. EPA will aggressively push compliance in 

states that have a high number of priority systems to address those systems.

2. Improve Data Quality

Data completeness and accuracy must remain a high priority for EPA and the primacy agencies. Without 

high quality data from primacy agencies, EPA cannot fulfill its responsibility to fully assess the state of 

compliance of the nation’s PWSs and to communicate to the public, Congress and other oversight bodies. 

Some of the next steps EPA, states, and the drinking water stakeholders have agreed to undertake include:

 Providing online error reporting on EPA’s ECHO (Enforcement and Compliance History Online, 

http://www.epa-echo.gov/echo/) web site containing data on PWS compliance; 

 Encouraging states to issue regular reminders to water systems of their compliance monitoring 

schedules;

 Negotiating grant conditions with several states to encourage them to follow quality assurance/quality 

control plans for drinking water violation data reported to EPA and address the differences in 

interpretation of the regulation; and

 Working with all states to implement the EPA Order CIO 2105.0 dealing with requirements for 

quality management systems.

3. Continue to Implement the 2009 Enforcement Response Policy

Primacy agencies will continue to pursue enforcement actions against violating PWSs - including those in 

Indian country - both to expeditiously return systems to compliance and to deter future violations. EPA 

and primacy agencies will continue to implement the 2009 ERP, which has already decreased the number 

of PWSs in significant noncompliance. 

EPA will continue to work with primacy agencies as they implement the ERP by providing training and 

support as needed.

20
4. Continue to Develop Capacity at Smaller Public Water Systems

EPA will continue its efforts to support PWSs serving 10,000 or fewer consumers through the capacity 

development program and other sustainability efforts. Recognizing the challenges facing these drinking 

water systems, EPA provides tools and assistance to develop system capacity (the technical, financial and 

managerial capacity of a system to provide safe drinking water). The program also provides information 

about treatment technology options for small systems. EPA’s capacity development efforts include:

 Numerous assistance activities, such as on-site visits and the distribution of easy-to-read guides and 

checklists.

 The Local Government Environmental Assistance Network (LGEAN) web site, a source of free 

information on current and developing SDWA requirements (as well as technical assistance, peer 

counseling, and financial guidance). LGEAN can be accessed on the internet at www.lgean.org or by 

calling toll-free 1-877-TO-LGEAN (865-4326). 

 The Financing for Environmental Compliance web site providing financial and technical assistance 

resources to help communities create a plan to finance environmental capital assets. The web site can 

be accessed at: http://www.epa.gov/compliance/assistance/financing/steps.

 Tools and resources assisting small PWSs with implementing drinking water regulations and 

managing their PWSs while providing adequate public health protection can be accessed at 

http://water.epa.gov/type/drink/pws/smallsystems/index.cfm.

 Additional tools and resources to support system sustainability can be accessed at 

http://water.epa.gov/infrastructure/sustain/index.cfm.

5. Continue to Increase Transparency of Data

EPA believes that raising the public’s awareness of the violations at PWSs will encourage PWSs to 

improve their compliance. In addition to the information in this report, data on the numbers and types of 

PWSs, populations served, source water, violations, enforcement actions and more are presented in 

various other formats on EPA’s public web site at the following URLs:

http://water.epa.gov/scitech/datait/databases/drink/sdwisfed/howtoaccessdata.cfm

http://www.epa.gov/enviro/

http://www.epa-otis.gov/echo/compliance_report_sdwa.html.

Readers should be aware that data in these reports and others using SDWIS/FED data may differ 

somewhat, depending on the specific queries used to generate each report.

without the limits of a state, and (c) all Indian allotments, the Indian titles to which have not been 

extinguished, including rights-of-way running through the same.

Interim Enhanced Surface Water Treatment Rule (IESWTR)

Applies to PWSs using surface water, or ground water under the direct influence of surface water, that

serve more than 10,000 persons. The rule also includes provisions for states to conduct sanitary surveys 

for surface water PWSs regardless of system size.

Large System

Large systems are those public water systems that serve more than 10,000 people. For purposes of this 

report, medium systems, which serve 3,301 to 10,000 people, are included in the discussions of large 

systems.

Lead and Copper Rule (LCR)

Requires a PWS to take steps to minimize the risk of exposure to lead and copper in drinking water by 

monitoring for these contaminants, installing corrosion control where required, and, where necessary, 

educating the public about ways to reduce exposure. A system may also be required to treat its source 

water or replace lead service lines.

Long Term 1 Enhanced Surface Water Treatment Rule (LT1ESWTR)

Strengthens control of microbial contaminants, particularly Cryptosporidium, for systems serving fewer 

than 10,000 consumers. It is the smaller system counterpart of the IESWTR.

Long Term 2 Enhanced Surface Water Treatment Rule (LT2ESWTR)

Targets additional Cryptosporidium treatment requirements to higher risk systems. 

Maximum Contaminant Level (MCL)

A-2
The maximum permissible level of a contaminant in water delivered to any user of a public water system.

Maximum Residual Disinfectant Level (MRDL)

The maximum permissible level of a residual disinfectant in water delivered to any user of a public water 

system.

Medium System

Medium systems are those public water systems that serve 3,301 to 10,000 people. For purposes of this 

report, medium systems are included in the discussions of large systems. 

Monitoring and Reporting Violation

Refers to either a violation of a monitoring and reporting schedule or a violation of contaminant-specific 

minimum testing schedules and operational reporting requirements. Those monitoring and reporting 

violations considered “significant” for the purposes of the state and national PWS compliance reports are 

described below in Table A–1.

National Primary Drinking Water Regulations (NPDWRs)

Legally enforceable standards that apply to public water systems. Primary standards protect public health 

by limiting the levels of contaminants in drinking water.

Non-transient Non-community Water System

A non-community PWS that regularly serves at least 25 of the same persons over six months per year. A 

typical example of a non-transient non-community water system is a school or an office building that has 

its own water source, such as a drinking water well.

Primacy

The SDWA requires EPA, states, and tribes to work as partners to ensure delivery of safe drinking water 

to the public. Any state or Indian Tribe can request responsibility for operation and oversight of the 

drinking water program within its borders. In order to receive this responsibility (called “primary 

enforcement authority” or “primacy”), a state or Tribe must show that, among other things, it has adopted 

drinking water regulations that are at least as stringent as federal regulations, and demonstrated its 

capacity both to enforce those regulations and to implement other activities necessary to ensure 

compliance.

In the absence of state or Tribal primacy, EPA assumes responsibility for administering the drinking 

water program for that area. Of the 56 eligible States (defined to include Commonwealths, Territories, 

and the District of Columbia), all but Wyoming and the District of Columbia have primacy. During 

calendar year 2012, the EPA Regional Offices administered the drinking water program within these two 

jurisdictions and on all Tribal lands, except for the Navajo Nation.

Public Notice (PN) Rule

The PN Rule requires all PWSs to notify their consumers any time a PWS violated a national primary 

drinking water regulation or has a situation posing a risk to public health. Notices must be provided to 

persons served (not just billing consumers).

Public Water System (PWS)

A system for the provision to the public of water for human consumption through pipes or other 

constructed conveyances, if such system has at least 15 service connections or regularly serves at least 25 

individuals at least 60 days out of the year. A public water system can be either a community water 

system, a non-transient non-community water system, or a transient non-community water system.

A-3
Public Water System Supervision (PWSS) program 

A program authorized by SDWA that supervises implementation of the SDWA regulatory requirements 

and thereby helps ensure that the public receives safe and adequate supplies of drinking water. 

Radionuclides

Radioactive particles, such as radium-226, radium-228, gross alpha, and beta particle/photon

radioactivity, can occur naturally in water or may result from human activity. EPA has established MCLs 

for uranium, beta/photon emitters, alpha emitters, and combined radium 226/228.

Safe Drinking Water Act (SDWA)

The main federal law that ensures the quality of Americans' drinking water. Under the SDWA, EPA sets 

standards for drinking water quality and oversees the states, localities, and water suppliers who implement 

those standards.

Safe Drinking Water Information System/Federal (SDWIS/FED)

The federal database that contains information submitted by states, EPA regions, and public water 

systems in conformance with reporting requirements established by the Safe Drinking Water Act 

(SDWA) and related regulations and guidance.

Significant Noncompliance

Violating PWSs identified as those that are the highest priority for enforcement. All unresolved 

violations not already under formal enforcement at each system are considered in the prioritization 

process. Acute health-based violations are weighted most heavily in the prioritization with minor 

violations weighted least. 

Significant Violations

Significant violations include all violations of health-based standards, including exceedances of 

Maximum Contaminant Levels (MCLs), Maximum Residual Disinfectant Level (MRDL), and violations 

of treatment technique rules; certain notification violations (i.e., complete failure to provide required 

notification); and major monitoring and reporting violations (failure to sample or to report results during a 

compliance period).

Small PWSs

Small systems, for purposes of this report, are those that serve no more than 3,300 consumers.

Surface Water Treatment Rule (SWTR)

The Surface Water Treatment Rule requires a public water system served by surface water or by ground

water under the influence of surface water to take steps (such as disinfection, filtration followed by 

disinfection, or watershed control) to reduce potential exposure to microbiological contamination.

Total Coliform Rule (TCR)

The Total Coliform Rule establishes limits on coliform bacteria in water distribution systems. Although 

coliform bacteria, which are found in decaying organic material and in the intestinal tract of humans and 

animals, are usually not harmful to human health, their presence may indicate the presence of other, more 

dangerous microbial contamination.

Total trihalomethanes (TTHM )

Widely occurring class of disinfection byproducts formed during disinfection with chlorine and 

chloramine. TTHM includes chloroform, bromoform, bromodichloromethane, and 

dibromochloromethane.

A-4
Transient Non-community Water System

A non-community water system that does not regularly serve at least 25 of the same persons over six 

months per year (Note – see 40 CFR 141.2). A typical example is a campground or a highway rest stop 

that has its own water source, such as a drinking water well.

Treatment Technique (TT)

In cases where EPA has determined it is not technically or economically feasible to establish an MCL, the 

Agency can instead specify a treatment technique. These are treatment methods required by EPA to 

minimize the level of a contaminant in drinking water.

Variances and Exemptions

A public water system that cannot comply with a drinking water standard because of poor source water 

quality, or, in the case of small PWSs, inadequate financial resources, can be granted a variance to 

comply with less stringent, but still protective standards based on a specific EPA-approved technology 

available to the system. An exemption allows a PWS with compelling circumstances (including 

economic considerations) additional time to achieve compliance with applicable SDWA requirements, so 

long as public health is adequately protected.

Appendix B

Summaries of Primacy Agency Annual

Compliance Reports

This Appendix presents a summary of each primacy agency report in a standardized format. The format 

includes an overall summary of the violations data specified in Section 1414 of the 1996 SDWA 

Amendments (i.e., violations with respect to MCLs, TT violations, significant monitoring and reporting 

requirements, significant notification violations and variances and exemptions).

This Appendix does not interpret the state reports. Therefore, other factors must be taken into account 

before drawing conclusions about a program. For example, PWSs are required to report all violations to 

the primacy agency, but drinking water programs vary in the regulations they choose to emphasize. A 

primacy agency that decided to focus attention and resources on one particular rule may have discovered 

and reported many more violations of that rule than a primacy agency that chose to focus on a different 

rule. A disproportionate number of violations in a state, commonwealth, territory, or tribe could also 

indicate that the primacy agency needs to work with its PWSs to improve their compliance. Readers are 

cautioned to view the violations data provided in the summaries within the context of each primacy 

agency and its individual drinking water program.

In 2012, EPA received Public Water System Compliance Reports from 43 of the 55 primacy states, 

commonwealths, territories and tribes. As in past years, American Samoa, Guam, the Northern Mariana 

Islands and Navajo Nation did not submit reports and, with limited exceptions, did not supply information 

to SDWIS/FED. EPA did not receive reports from 12 primacy agencies as indicated in Table B-1. 

Appendix B supplies what information is available in SDWIS/FED to indicate violations at public water 

systems in the states, commonwealths, territories and tribes that did not submit compliance reports in 

2012.

EPA prepared reports for the District of Columbia and Wyoming, which did not have primary 

enforcement responsibility for drinking water in calendar year 2012.

Violations for 2012

EPA summarizes the number of MCL, MDRL, TT and significant monitoring and reporting violations14

reported by each state in six categories:

• Violations of chemical contaminant requirements15;

• Violations of the Total Coliform Rule;

• Violations of the Surface Water Treatment Rule, Interim Enhanced Surface Water Treatment Rule, 

Long Term 1 Enhanced Surface Water Treatment Rule, Long Term 2 Enhanced Surface Water Rule

and Filter Backwash Recycling Rule;

• Violations of the Lead and Copper Rule;

• Significant Notification or Consumer Confidence Rule Violations; and

• Violations of the Disinfection and Disinfectant Byproducts Rules.

EPA summarizes the numbers of individual public water systems in violation in each of these six categories, as 

reported by the state. If a state’s report did not include information in a category, EPA’s summary notes the 

14 A comprehensive definition of significant monitoring and reporting violations appears in Appendix A.

15 MCL and significant monitoring violations for organic, inorganic, nitrate and nitrite, and radionuclide contaminants. 

B-1

 
omission.

2012 Totals

EPA also summarizes the total number of systems in each state, the total number of significant violations 

reported and the total number of PWSs in violation, if the state reported this information. When states did 

not provide information on the total number of public water systems, EPA supplied that information from 

the SDWIS/FED.

Systems in Violation

Systems in violation are defined as the number of different systems with a reported violation of this type. 

Some states counted a system with multiple violations or violations in more than one category as one 

violating system. Other states counted a violating system each time it had a violation, or once for each of 

the regulatory categories in which it had a violation. If EPA’s review of a state’s report indicated some 

violating systems were counted more than once, an asterisk notes that the state’s number possibly over 

counts violating systems.

Variances and Exemptions

Five violations of variances or exemptions were reported by the primacy agencies during 2012.

Where to Obtain the 2012 Annual Public Water Systems Report

If a primacy agency’s report includes information on how to obtain a copy of the report, the information is 

provided on the primacy agency’s summary page in this Appendix. In addition, Table B-3 presents a 

summary of the primacy agency reports available on the Internet. In some cases, the web site provided by 

the primacy agency does not contain the 2012 report. These web sites are still included in the summary 

table.
